"Assuming the mag is the grip, its facing the wrong direction, right?
Are there pics from different angles? Or is this a joke of some sort"
Grizz,
No, the magazine is NOT the grip.
It takes a standard AR-15-style pistol grip, which is not attached in that photo.
The round ring to the left of the picture is where the buttstock and recoil buffer assemblies attach. Under that, the milled flat area, is where the pistol grip attaches.
